I think filestube give API key to get their search result. Also they provide a template. use google to find it. But its better to coding it your self, you can make it unique. Me, i'm coded www.avun.com to compete with filetube

Well we had started out using the rapidshot scrip for our Link Generator but about a week ago we changed over to a unique script which albeit did cost a reasonable amount to develop we feel that offering a multi link generator will br better in the long run.Only trouble that we can see at the moment is the server bandwidth is taking a massive hit so we will have to expand that.
